Ashcroft 451259 Process Gauge

The Ashcroft 451259 is a process pressure gauge built for monitoring fluid or gas systems up to 60 psi. Its 4 1/2 inch dial provides clear readings for plant operators and maintenance technicians. The black polybutylene terephthalate case houses a glass lens and white dial face. A 1/2 inch male NPT bottom connection fits standard process piping.

Accuracy limits and environmental fit

The gauge delivers an accuracy of +/- 0.5 percent of span across the 0 to 60 psi range. No IP or NEMA rating is assigned, so the instrument is not certified for wash-down or outdoor exposure. The dry case lacks liquid dampening and offers no specified vibration resistance. Fields cannot be filled with glycerine or silicone after installation.

Capacity headroom and use boundaries

The 60 psi upper limit suits low-pressure air, water, and hydraulic lines with adequate safety margin. Systems that regularly exceed 60 psi or experience sharp pressure spikes need a higher-range gauge. The fixed 1/2 inch NPT male bottom mount cannot be reoriented or adapted without extra fittings. Users requiring panel mounting, front flanges, or field-fillable dampening must select a different model.

Questions about this item

Should I pick the 4 1/2 in dial or a smaller size for panel mounting?

The 4 1/2 in dial gives a larger reading area at +/- 0.5 percent accuracy, which is easier to read from a distance on process panels.

What does the 0 to 60 psi range mean for daily use on a hydraulic line?

It measures up to 60 psi continuously; the +/- 0.5 percent accuracy stays valid across the full span, so readings remain reliable at working pressure.

Will the 1/2 in NPT male connection thread into my existing port without an adapter?

Yes, the 1/2 in NPT male bottom connection mates directly with a matching 1/2 in NPT female port; no adapter is required.
